linux下redis启动停止脚本

脚本参数:

        redis -p [port]  [start|stop|status|restart]

              参数说明：

          -p [port] : 指定redis实例的端口，用于多实例的服务器

         start：启动指定端口的Redis服务

         stop：停止指定端口的Redis服务

        status：进程状态

       restart：先关闭Redis服务,再启动Redis服务

      注：不指定端口时，脚本默认指定启动6379端口的redis

用法实例：

    service redis -p 6381 start  #启动6381端口实例的redis

   /etc/init.d/redis  start  #默认启动6379端口实例的redis

代码:

#!/bin/bash
#chkconfig: 2345 55 25
